ITPEC IP April 2025 Question 40
ITPEC IP April 2025 — Question 40 of 100
Fingerprint authentication — it verifies a physical characteristic of the person.
Biometric authentication uses measurable human traits, such as fingerprints, facial features, iris patterns, or voice characteristics. A fingerprint is therefore an inherence factor: something the user is, rather than something the user possesses or knows.
Answer (a)
Why not others:
- (b) Digital certificate is a credential associated with a key and is treated as a possession factor
- (c) Personal ID card is also something the user has
- (d) One-time password is a temporary secret, usually generated or delivered through another authentication mechanism
Key rule: Authentication factors are commonly grouped as knowledge, possession, and inherence; biometrics belong to inherence.
